Have no complaints other then each time i do a water change i have to disconnect it and when i re connect it wants to go over the sensor because im dumping water in too quickly. Very easy to use, no issues with it whatsoever. I have one on both of my tanks

Easy to install and to use. Very strong magnet so you don't need to worry about it falling.

This ATO was so easy to install and it is worth the price. Matching pump takes the guess work out. The best feature I like is the electronic eye. It works like a charm and the magnetic holder far surpasses those models with suction cups.

I own two of these and really like them. The magnet mounts are very secure and prevent te switches from moving.

The Tunze Osmolater is definitely a good investment to have. I bought one for my 75 gal tank and I am strongly considering one for my other smaller salt tank. They work great !

You won't be disappointed with this purchase. You could buy a cheaper way of topping off but when you run dry and burn a pump up the one time you leave the house for more than 6 hours or flood your room you'll wish you had bought this unit.
i keep the standard float valve nice and clean by running the top off water on it. keeps any salt build up off and the other electronic eye you got no worries about. Perfect setup and i feel confident in leaving for days on end without worry.

The build quality was very good ad the factory support has been great too. I will soon be adding another Tunze 3155 to one of my other tanks

Well constructed with magnets that will hold it wherever you want. Works well in a RSM 130D.

Although this product is one of the more expensive top-off systems, you have so much already invested that it is nice not to rely solely on float switches and flood your house. Worth the extra cash in my opinion.

Overall it is a great product. I have not experienced any malfunctions and the holder for the float switch and eye is very convenient. It does what it is supposed to do. However, I do have a few complaints.

1) The pump automatically pumps about a cup of water each time the pump is turned off. That means, if you dose kalk with your ATO as I do and your APEX turn the pump off because the pH is too high, as soon as it turns back on it pumps more high pH into the tank. Not a good feature. I'm sure it's to maintain constant flow through the tubing after it has been resting, but a manual button for this would be better

2) When the ATO alarm goes off, the only way to turn it off is to power down the ATO. Which means when you turn it back on, AGAGIN, it pumps more water into your tank. A button for this would also be better.

3) Eh...I guess it could be a little more attractive. Kind of an ugly black box.

Finally got around to setting this up yesterday and it was easy as cake. 5 minutes out of the box and rolling. Everything you need for easy, dependability, and redundancy - could not have asked for a better ATO. Must have.
